wrt54g v2 as access point instead of router?

    Hey everyone :) I have 2 WRT54G v2's at the office that I'm trying to setup to work as access points instead of their normal router function. I feel like I've tried everything and simply can't get it to work.

    The office runs on a separate router downstairs that takes care of all of the DHCP/Static DHCP functions in the office and I would simply like for the WRT54G (when plugged into an ethernet port on the second floor) to act as an access point that would route wireless traffic to the router downstairs and allow that router to work its DHCP magic. This wouldn't be a big deal if the office didn't rely heavily upon the fact that the ip address of each computer dictates much of the security in terms of connecting within the office (assistants to brokers and whatnot).

    I'm at a loss at this point and am a total newbie to the whole linksys hacking stuff so I was hoping that one of you might be kind enough to help me out with this one.

    Again, to recap... I simply want to be able to plug the WRT54G v2 router into the office router and have it work to route wireless requests over to the office router for DHCP functions. If this is possible... I may be the happiest man alive.

    Thanks in advance!
    -Stephen

    All you need to do is disable the DHCP server in the web interface. It's been so long since I actually looked in the Linksys stock firmware (!), I forget where it is, but it is definitely there!

    Then connect one of the LAN ports on the WRT54G to your LAN and you should be golden.

    You have to change the setting in advanced routing from gateway to router also and change the local address of the router if it conflicts with the othe WRT54G v2.0. The local address you are using as a access point should be on the same subnet, but out of the range of the DHCP server. For example, it the other has a local address of 192,168,1,1, change the address pf the onte you are using as a access point to 192.168.1.2.

    Thanks for the advice guys... here are a few more questions:

    To: Bluebox - If I connect one of the LAN ports and not the Wan port to my lan... will it route the computers over to my old router? I feel like hooking a lan port to the office router won't do anything... maybe i'm missing a step somewhere?


    To: Howard - The office router has an ip address of 10.0.1.9. I need to make sure that the office computers that connect wirelessly will be able to see all the other computers in 'my network places'. The office router hands out DHCP addresses between 10.0.1.90 and 10.0.1.250. What ip address should I give the WRT54G V2 so that it doesn't conflict with the office router, but instead gives the office router the say in assigning DHCP addresses to wireless clients?

    the way to convert a router to an access point is pull the uplink connection from the wan port and put it into one of the lan ports. thats it :) this simply creates a bridge between the lan side and wireless side, as if everything was plugged into the same switch.
    of course you will want to disable any services that are being provided elsewhere (like dhcp) and make sure that the device's ip address do not conflict with anything else on the network. all you are doing here is making sure that 2 devices dont end up with the same ip, and this one will only be used for remote management.
    some of the 3rd party firmwares allow you to do some extra stuff like use the wan port as an additional lan port, or disable it entirely.

    Give the WRT54G an address of 10.0.1.11 to 10.0.1.89 or higher than 10.0.1.250. By coonecting the WRT54G by one of its LAN ports instead of it WAN port it is acting as a wireless hub..
